Low Potassium Content Vegetables in End-Stage Renal Disease

Hyperkalemia is common in End-Stage Renal Disease on chronic hemodialysis patients. The most common cause of mortality in End-Stage Renal Disease patients is sudden cardiac death caused by hyperkalemia. Hyperkalemia also increased urgent dialysis and hospitalization rate. Thus, the management for hyperkalemia in End-Stage Renal Disease patients is crucial, including restricting dietary potassium, medication control, and dialysis dosage adjustment. In the ordinary diet, the significant sources of potassium are vegetables and fruit. In our study, the investigators try to find out the influence of low potassium content vegetables for serum potassium control in End-Stage Renal Disease on chronic hemodialysis patients. This study is a prospective cohort study; the investigators enroll forty End-Stage Renal Disease on hemodialysis patients and perform this study in eight weeks period. The investigators conduct a randomized, double-blind and cross-over trial for investigating the influence of low potassium content vegetables on End-Stage Renal Disease patients. The serum potassium level will record under different potassium content vegetables. The possible adverse effects of low potassium content vegetables, cardiac arrhythmia, will also obtain by chart records during this study.
